. To all whom it may concern:

Be it known that I, Jnssn W. WAGNER, a citizen of the United States, residing at Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Artificial Stone, of which the following is a specification.

The present invention relates to the production of artificial tomb stones, railings, etc., from a plastic compound, and my object is to. produce a compound of this character, which after being cast or molded in the desired form is impervious to moisture and will not disintegrate in cold weather.

In carrying out the invention, I mix the following ingredients in substantially the proportions specified;

Asbestos fiber 15 lbs. Ground asbestos 235 Grease 16 Ground mussel shells 6 Hemp fiber J; Glue 1 Portland cement.. 150

The ground asbestos and the Portland cement constitute the main body portion of the compound, while the asbestos fiber and the hemp fiber constitute a binder for holding the body portion together and preventing any cracking or breakingi up of the finished product. The groun renders the compound fire-proof. The grease renders the composition water-proof, and the glue keeps said grease from ing drawn to the surface, durmgwarm weather by capillary attraction while the composition 1s hardening. The ground mussel 'shellsare employed principally as a decorative feature; A suflicient quantity of water is added to the ingredients to make tmpound plastic and to cause the cementto set in the usual manner. The plastic compound is then molded in the desired shape and permitted to harden. The tomb stones or other shapes Specification of Letters Patent.

asbestos also Patented Mar. 2, 1915.

which are molded as above set fo have the advantage of being frost-proof and of not absorbing water, so that they are not sub ect to disintegration in cold weather, and do not increase in weight during moist weather.

In the preferred form of forming the compound, the hemp fib'er, the Portland cement, the mussel shells, and the glue, which has been previously dissolved in water, arev mixed in the required proportions. The asbestos fiber, the ground asbestos, and the grease are then added, the grease first being heated to a boiling state so that it will thoroughly permeate the compound, and the whole is thoroughly mixed together. Water is then added to render the composition sufficiently lastic to be molded into any desired form. y desired coloring matter be added.

en desired, the composition may be employed as a stucco over a hollow core, instead of being molded in solid form. Having thus described my invention,what I claim and desire to secure by Letters Patent is:

1. A new composition of matter for the purpose described, comprising asbestos fiber JESSE w. WAGNER.
